Early Life
Sergei Korolev was born in 1907 in what is now Ukraine, which was then part of the Soviet Union. As a child, he loved machines, airplanes, and anything that could fly.
He enjoyed building models and dreaming about the sky. These early interests helped him imagine a future where humans could travel into space.
Learning and Big Dreams
Sergei studied engineering and became very good at math and problem-solving. He believed that rockets could travel far beyond Earth.
At a time when space travel sounded like science fiction, Sergei worked hard to turn these ideas into real machines.
The Space Pioneer
Sergei Korolev became the main leader of the Soviet space program. He was known as the "Chief Designer," but his name was kept secret from the public for many years.

This historic flight showed that humans could survive and work in space. It inspired millions of people to dream bigger about science and exploration.
Building Rockets and Hope
Sergei helped design powerful rockets that could lift heavy spacecraft. These rockets became the foundation for many future space missions.
He believed space exploration should help all humanity learn more about the universe and about Earth itself.
